Brian,

The Sample Code disks (yes, there are two in the next batch) will contain
a sample chock(sp?) full of SF samples. In the meantime, you should be able to
do what you want. Without seeing your program, I don't know for sure what is
going on, or even which filter your are trying to use (there are actually 3).
If you are really using the ModalDialog filter, then it sounds like you aren't
returning TRUE, saying that you didn't handle the event and that someone else
should. In this case, that someone else is Standard File.

I demonstrate all 3 kinds of filtering in this sample program, so you should be
able to find what you need there. It is on Phil and Dave's Excellent CD, which
will be mailed to all developers soon (if you didn't get it at the Developer's
Conference).
